The amount of grease injected into the bearing affects the use of the bearing

For sealed bearings, the proper grease is filled at the time of production; in the case of open bearings, a sealing device is also provided in the main machine to prevent leakage of grease.

This has a problem of how much grease is injected into the bearing.

If the amount of grease is too small, it may cause fat or dry friction and affect the life. Excessive grease injection will cause the bearing temperature to rise. A large amount of grease leaks both pollutes the environment and wastes. It can be seen that the amount of grease injected into the bearing is as small as possible while ensuring sufficient lubrication of the bearing.

Bearing damage and countermeasures

Core Tip: Damage to the bearing: Generally, if the bearing is used correctly, it can be used until the fatigue life is reached. However, there will be accidents that are prematurely damaged and cannot be used. Early damage
Bearing damage:

In general, if the bearing is used correctly, it can be used until the fatigue life is reached. However, there will be accidents that are prematurely damaged and cannot be used. This early damage, as opposed to fatigue life, is a quality use limit called a fault or accident. Many of them are caused by inadvertent installation, use, and lubrication, and foreign objects intruding from the outside are insufficiently studied for the thermal effects of the shaft and the outer casing.

Regarding the damage state of the bearing, such as the ferrule of the roller bearing and the jam of the rib, it may be considered as a cause of insufficient lubricant, unsuitability, defects in the oil supply structure, intrusion of foreign matter, bearing installation error, shaft deflection If the song is too big, there will be coincidences of these reasons.

Therefore, it is difficult to know the true cause of the damage by only investigating the bearing damage. However, if you know the mechanical use of the bearing, the conditions of use, the structure around the bearing, and the situation before and after the accident, combined with the damage state of the bearing and several reasons, it can prevent similar accidents from happening again.
